I took a notion tonight to try bridling Willow the old-fashioned way, but from the off side. Lo and behold, she let me do it! She was slightly concerned about her ears, but nothing like she had been. In about five seconds, the bridle was on. I didn't actually give her a million sugar cubes; it was more like eight. Now we'll have to see if she lets me do it again tomorrow--it's possible I surprised her into compliance tonight.
Maybe I'll be able to ditch the twist ties and reattach the browband before long.
